1. The Disciplinary Mind: the mastery of major schools of thought, including science, mathematics, and history, and of at least one professional craft;
2. The Synthesizing Mind: the ability to integrate ideas from different disciplines or spheres into a coherent whole and to communicate that integration to others;
3. The Creating Mind: the capacity to uncover and clarify new problems, questions and phenomena;
4. The Respectful Mind: awareness of and appreciation for differences among human beings and human groups;
5. The Ethical Mind: fulfillment of one’s responsibilities as a worker and as a citizen.
Gardner makes the striking point that the Synthesizing Mind is becoming more important than ever, given our highly technological, highly informational world. The Disciplinary Mind — or what we think of as classical intelligence, the stuff child prodigies are made of — has dominated the intellectual landscape throughout history. But, Gardner argues, now that the Internet, technology, and media are making massive amounts of very dense information available to the average person, the type of mind that can acquire and store information is still impressive, but ultimately less useful than a mind that can process, connect, and communicate cross-disciplinary information to others in a meaningful way.
Thanks to the Internet, everyone can now access the vast storehouses of intellectual wealth that once belonged only to a concentrated elite. It makes sense, then, that the new elite could turn out to be those who can receive information rapidly, sift it, connect the dots, and put the whole picture to the best possible use for others.
In my mind, the Synthesizer concept parallels entrepreneurship in a few interesting ways. Just as information can behave like a type of good or service, it seems a person with a Synthesizing Mind can make prudent use of knowledge for the good of the entire human community. Technology makes it possible for the Synthesizer quickly to select the most relevant material from the experts — who have divided their labor to manage whole disciplines and systems of thought — without laboring to build a monolithic knowledge base of every field on his own, which would take a long time and allow him to share only a few authoritative insights at the end of all his pursuits. This does not mean the Synthesizer hurries or skips over important steps: he still must be a careful scholar who humbly stands “on the shoulders of giants,” as Sir Isaac Newton put it. It simply means he is free to use his creative powers to illuminate more readily for others the way various disciplines interact and the consequences they have for human life. That in turn makes him able to harness and combine the talents of others to form a serviceable “product” faster than a person with a Disciplinary Mind.
If thinking truly is “connecting things,” as G.K. Chesterton wrote in Orthodoxy, the concept of the Synthesizing Mind has a great deal to offer to people of every category of intelligence. Even if you disagree with Gardner’s categorizations, having a Synthesizing Mind might help you to figure out why.
